A basic 11/24 processor uses 22-bit addressing but a Unibus uses 18-bit addressing and therefore can address up to 256KB; the top four bits of address are therefore dropped by the MMU in a basic 11/24. If it's fitted with a Unibus Map (KT24, M7134, which also replaces the M9312 bootstrap card) then an 11/24 can use 22-bit addressing, on an extended Unibus, giving it a 4MB address space. It does this by feeding the output of the MMU through 31 mapping registers which provide relocation, so at any given moment you can actually only address 31 pages, each of 4KW (8KB), plus the I/O page; you need to re-program the mapping registers or the MMU to access the whole 22-bit range. I don't know where the 1MB limit comes from, that would be a 20-bit address range. > Furthermore, does a DELUA - Card properly work in it ? > There's only the card, the bulkhead assembly is missing, I would have to build it by myself...

Questions about the PDP 11/24

by cheri-post＠web.de

Hello all, does anybody know, how much memory the 11/24 can take ? I heard something about 1 MB, others say 4 MB somewhere on the web. Yes, I'm a bit confused... Currently, it's configured with 1 MB. Furthermore, does a DELUA - Card properly work in it ? There's only the card, the bulkhead assembly is missing, I would have to build it by myself...

Macintosh collector groups?

by vaxlion＠postal.lionsden.com

Howdy all, I have two Macs, a Mac IIsi and 7200, I would like to get rid of. Does anyone have any recommendation for a Mac collectors group that might have some individuals interested in these machines? Listings for these machines on both Ebay and Vintage Marketplace have yeilded no takers. Thanks, -- Michael

Got a HP 2648. Now what?

by jdbryan＠acm.org

Bob, On Thu Dec 9, 2004, you wrote: > Its kinda odd how these terminals 'wake-up' with the text input > directed to the graphical display rather than the alpha display layer. That shouldn't happen unless the Keyboard Interface PCA is strapped for "compatibility mode." Open the unit, pull the Keyboard PCA, and check the DIP switches at the top of the card. Switches P and Q should be set to 0 (closed) for normal operation. With both closed, the terminal should power up in alpha text mode. Then it may be switched to graphics text via an escape sequence or by the keyboard TEXT key, as desired. (I have an HP 2647A. P and/or Q are set to emulate a Textronix graphics terminal.) -- Dave

Panasonic 805 Calculator

by cb＠mythtech.net

>That is almost certainly vacuum fluorescent. There are a lot of such >displays that use the same kind of seven-segment number formation you >commonly see with LEDs. Yes, I did more digging and found a web site specializing in vintage calculators, and it had a full discussion on the different types of displays... and yes, it does appear that I have Vacuum Fluorescent Display Tubes. This was reaffirmed with a closer inspection (with the aid of a flashlight) and each of the segments appears to be an individual tube (you can see the curves of the front as well as the typical peaked top). I've yet to open it to see if they are socketed or soldered... I figured I'd leave that until I new more about the technology and if the tubes are repairable, or if I can get the correct replacement part. -chris <http://www.mythtech.net>

LF: VT-180 parts

by dave04a＠dunfield.com

Hi again Guys, Had a VT-180 show up on my doorstep last week, and knowing another local collector who had one in "unknown condition", I decided to spend some time working on the two machines. Good news is that I have both of them working and booting up. But there are assorted bits and pieces missing, if anyone happens to have any of these VT-180 parts kicking around, please let me know: - One machine is missing the drive cable (the data cable from the VT-180 to the RX-180 disk unit) - One machine is missing the metal back cover/shield for the card cage - Both machines are missing the plastic shroud which covers the above mentioned cover/shield and connectors. - Both machines have "VT-100" nameplates - would like to find the VT-180 nameplates. - One machine is missing the ESC and '3' keys from the keyboard - this is a standard VT-100 keyboard, so keys from a VT-100 would also be a perfect match.

I know this is a bad subject, but I was reading an article about windows nt and the influence dec had on it. In the article it said that compaq kept development of windows 2000 up to 1999 on Alphas. Has anyone here seen it running on an Alpha and do you know if many people developed software to run on it. I knew they had NT on a lot of architectures but 2000 is a new one. Thanks Dan

MDS 225 Update

by melamy＠earthlink.net

I second the spare parts threat... no need. As for the cable pinout, I may have it with me (I just flew into Seattle from Virginia for the holidays). If I don't then I can email the connection scheme when I get back after the 2nd of January. I detailed not only the external cable, but the internal cable to make the internal drive a double density. I can send iPDS disks after I get back on the 2nd also. I'm with Dave, no need to replace the internal drive. Leave all the hardware as-is for now. The double density is the controller - not the drive. best regards, Steve Thatcher

Differential Analysers and Scientific American

by ljw-cctech＠ljw.me.uk

>From the most recent 'Computer Collector' newsletter (http://news.computercollector.com): > Early Nov., 2004: At the recent VCF 7.0 event, Tim Robinson displayed > Meccano versions of Charles Babbage's Difference Engine and Vannevar > Bush's Differential Analyzer (http://www.meccano.us). It's nice to see Evan has mentioned this lovely Differential Analyser, and I am sorry I missed seeing it (thanks especially to Erik Klein for his nice photos of it, http://www.vintage-computer.com/vcf7.shtml, which first alerted me to its having been there). Many years ago (1980) I made myself a simple two-integrator Differential Analyser, which worked on exactly the same principle. I was inspired by the Meccano machine which was on display at the Museum of Transport and Technology in Auckland - this was one of a number of similar machines made in the '30s - and found a construction article in the Amateur Scientist column of Scientific American. I was wondering whether anyone here with '70s issues of SciAm might be able to make a copy, or at least give a definite date for it. It would have been in the early-to-mid '70s, certainly before '78. Thanks, and if anyone still hasn't seen Tim's machine, go to www.meccano.us and prepare to be amazed.

MDS 225 Update

by river＠zip.com.au

Hi, Dear people, I do apologise if my attitude came across that "I'm gonna rip this apart for spares if I can't fix it", or if I came across aggressive. It was not my intent to antagonise, nor was it my desire to induce sympathy. Unfortunately the written word often lacks the character and nuances of speech. So, let me rephrase.... I purchased an old Intel MDS Series-4, specificaly for spare parts for my operating MDS Series4. The advertised unit has a memory error, but the rest of it checks out fine. My preference is to try and fix the broken unit. However, should my main unit have a problem I can always use the busted one to be a donor. If anyone knows exactly what chip 0000:8001 refers to (when doing a RAM test), then I will replace the offending component and have this unit fully operational. Which will make me a happy chappy. When I went to collect the unit the seller also said I could have the 225 unit. I spent a lot of time cleaning dirt and mud out of the 225 and then searched the internet for information. My intent was, and still is, to get this old beast running as good as they day it was made. If it wasn't, then I would of not bothered to take the unit or search for info on it, or come to this forum for advice. My comment, regarding "using it for spares" merely means it will be put away, somewhere safe and sound with all my other old stuff - some of which I have had to use for donor chips to get some SBC and other boards operational. It would indeed be a sad, sad day that I would need to pull it apart for bits. Once again, I apologise if my comments caused you angst. Now, back to the 225 issue. Yes, the disk drive array is a blue-box, twin-floppy unit that sits atop the main unit. The main unit has the two-board set that is required to run this double-density drive array. I have contacted the seller to ensure there isn't a cable left behind. Hopefully he has it still and that will be great. If not, I am more than happy to wait for pin-outs and, once supplied, I will make the cable. The other blue-box is the expansion chasis that sits under the main unit to give it a few more slots. I haven't powered up or even cleaned the disk-drive or expansion unit yet. They'll be done during the week. In the interim, I'm reading through the pdf files that you have kindly pointed me to. As per your advice, I won't be pulling apart the unit or do anything untoward until I get more information regarding boot disks and cable pinouts. The iPDS was a freebie given to me when I purchased my initial MDS Series4 some years ago. I have found very little information on this unit and therefore it has been set aside and I thought, "why not ask about the iPDS while I'm here" and it's good to see that there are some people out there that can help me get this unit operational. Other than that, I have no idea about this box - though I'd dearly love to get it going. I do have an old 486 DOS machine with 3 and 5 inch diskette drives, so I can get the iPDS disks done on that machine. My aim, with all this old stuff is to fix it as my main task. I don't collect things (like chip collectors) for looks. I like and want (almost have an inbuilt urge) to make it work and I love to have them all operational. I have fixed and have operational my old SC/MP, 6800 Micro Module, Central Data 2650, AIM65, STD bus and various Intel SBC systems - however, the old TI99/189 system (and a few others) have eluded me for quite some time, but I won't give up on them. Furthermore, I have an inventory of old processors, memory and peripheral chips and, using the Series4 with ICE85B, I build 8085 systems. I am hoping the 225 gets operational so I can do some stuff with the 8080 chip - like do some old S100 work and repairs on an SBC80/24. I'd love to build an 8080 system also. So please, don't think of me as a destroyer of old systems. I'm a preserver, who should of used a better phrase than "used for spare parts". :) I do hope you accept my apology, and I am extremely grateful for your assistance and advice. seeyuzz river

MDS 225 Update

by river＠zip.com.au

Hi, Thanks for the reply. I went and loaded all those docos regarding the Series 2XX. Great stuff. I cleaned up the connectors to the IO board and now the floppy drive engages upon reset. I ran the diags and all system work and even the floppy drive passed its tests with a scratch disk. However, I get a disk error when I boot the ISIS-II system disk. I tried a few other disks and the ones that are double-density all give a "disk error", yet the single-density ones just say "not bootable". So, I guess I need to find a single density 8-inch ISIS-II boot disk. I can't use the one from my Series-4 'cos it uses 5-1/4 disks. THe unit also came with a dual disk drive array - yet another amazingly heavy blue box, and an expansion chasis. It appears that there are no cables to attach the disk array. The 225 has the two disk controller cards in the chasis and the cables are routed to the J8/J9 connectors, but I beleive there is a cable that I require to attach from these connectors to the disk array. I'd love to get the 225 fully operational 'cos it came with the ICE-80 (which I cannot use on the Series-4, which has an ICE-85B), ICE-51 and ICE-49. I especially want to use the ICE-80 so I can do some 8080 development (may as well use the stock of chips I got). I'm gonna see if I can pull out the single-density drive in the 225 and put in one of the double density drives from the array. However, before I do that, does anyone know the cable pinouts - 'cos I might try and make a cable first. Or does anyone know where I can get a cable? In the final run, if I can't do anything much with it, I can always use the parts for spares and other stuff. Oh, final question... I also have an iPDS that's been waiting for a boot disk. Can I use my Series-4 ISIS-II disks in this unit? Will it boot, or is this unit doomed to be pulled apart for spares also? seeyuzz river

>Are you sure it's a LED display? That sounds more like behavior I would >expect of a vacuum fluorescent display. If an LED really is doing that, >the problem is with the electronics, not the diplay. I can't be sure. I didn't think it was an LED (the unit is from around 1970 or so), but when I looked at it a little while ago, it looked kind of like LED segments behind the plastic lens. They glow a bluish green if that is any help. They don't look like any LED out today, that's for sure. I've never knowingly seen a vacuum fluorescent display, so I can't compare. If this is one, is it a problem that is fixable? -chris <http://www.mythtech.net>

Votrax PSS Manual

by lord_nightmare＠users.sourceforge.net

I recently obtained a Votrax PSS which did not include the power supply or the manual. Thanks to Robert Stek's informative post (http://www.classiccmp.org/pipermail/cctech/2003-February/010608.html) on this list in feb '03, I am in the process of constructing a power supply for it. However, I still need a copy of the manual, so I can figure out how to set the various modes of the device, and control the AY-3-8910 audio generator chip. If anyone has the manual for the Votrax Personal Sound System and has some means to scan or digitize it (a digital camera will work) can they send me a copy of the images? It would be much appreciated. Jonathan Gevaryahu lord_nightmare_(a)t_users.sf.net (remove the _@t_ and replace with @ to demangle the address)

Panasonic 805 Calculator

by cb＠mythtech.net

My father has a very much loved Panasonic 805 calculator. However, in recent months, one of the LED segments has begun to misbehave. It is getting steadily worse. What happens is, in general the segment is dim, and once a segment lights, it doesn't seem to turn back off until you clear the calculation. As a result, very quickly, the one segment just stays on 8. Since this is the ones column, it effects all calculation displays (the calculation itself works fine, it always knows what the number should be, it is just the display of that number that doesn't work). Does anyone have any repair info on this calculator? Schematics or otherwise? I'd love to be able to open it and replace the segment, or whatever may be misfiring to cause it to display wrong. He hates to give it up, but he is finding it increasingly hard to use. -chris <http://www.mythtech.net>

Hmm, would probably have to be a FOONLY running TENEX or something of that era, I don't think VAXen running 4BSD quite cut it. For the record I run MicroVAX III's with 4.3BSD-Quasijarus, but I really hope that I'm not the oldest and that there are some people running plain 4.3 or even 4.2 on an 11/7xx connected to the net. Hell, since mine are all MicroVAX III's, even someone with a MicroVAX II will beat me. But then I will probably be putting together a new router soon and that one will have a MicroVAX II CPU, so at least I'll have that. MS

This measurement is difficult, because the top of the collar does not protude through the front panel, and in fact does not come all the way through to the face of the panel.

Final CP/M-80 diskette inventory

by tomj＠wps.com

I got the last box of junk from my brother, and just inventoried the floppies, going by the labels. I likely have errors in sidedness/density but they were all made on one of two CP/M machines; I have one here and the other (my father's) is still in Mass and I can get it if necessary. I have no idea whats actually on them or which ones are readable, that come snext after I power up the cards. I've gone through the chassis already and it's fine. I'll probably do smoke tests today. There's some good stuff I think. BDS C, CBBS from 81 (sources plus BBS files), Stackworth FORTH, JRT Pascal, some other Pascal, Aztec C, FORTRAN IV (likely TDL/Xitan), F80, M80, L80, etc (m'soft) basic compiler (ugh) old DBASE, etc...

WTB: DECstation 5000/1xx

by sethm＠loomcom.com

I'm looking for a DECstation 5000, a fairly recent and marginally classic MIPS workstation DEC sold in the early 1990s. (Well, it's classic to me for nostalgia reasons, but I won't get into that). I'm specifically looking for a 5000/133 or /150, but really any 5000 will do. I'd be happy to pay shipping and a reasonable price (reasonable being something in the < $50 range, since that seems to be the going rate), and/or I have a MicroVAX 3100 (desktop case, 16MB RAM, 1GB disk, 8 serial lines) I'd be happy to trade. If anyone has a lead on one, please let me know! -Seth -- "It looks just like a Telefunken U47! Seth Morabito You'll love it." - Frank Zappa sethm(a)loomcom.com

Need help with 2 projects (TI and Xerox)

by truthanl＠columbus.rr.com

Marty Greene, There are others of us who have TI 990/systems in storage. I have 2 990/10 systems. DX-10 OS with 10M cartridge (CDC?)drives. Mine came from a Paradyne Corp Modem Analysis system tracking 300 Paradyne 2400 Baud multi-drop circuits on an 800 hz subcarrier over dedicated lines. So I have lots of serial ports...Each modem had data and an analysis port. Sincerely Larry Truthan I may also have a Xerox Sigma diagnostics tape and or journal somewhere in the basement.

electro-Physics: 17.3409 volts

At 02:55 PM 12/13/2004, you wrote: >the only sound physical reason for fractions is cooking... the general populace is so technically illiterate that is really doesn't make a difference whether things are in fractions or decimal. They really don't have a clue anyway. When was the last time you heard any clerk actually count change out or someone realize that 1/4 cup is 1/2 of a 1/2 cup... But measuring by volume isn't necessarily the best method, either, particularly for flours that vary in volume depending on how long they've been sitting, the weather, or whether they've been sifted. They teach fractions like that in third or fourth grade. There's no excuse. - John P.S. Watch for me on the Food Network's "The Next Food Network Star" contest.

electro-Physics: 17.3409 volts

by dwight.elvey＠amd.com

>From: "Paul Koning" <pkoning(a)equallogic.com> ---snip--- > >Some of this discussion reminds me of the "arguments" why the metric >system is inferior to the US system of measures. Contrary to what Tom Jennings states in a later post, there are sound physical reasons for using fractional systems when dealing with the physical world. I'm not defending the English system that is a hodgepodge of poorly related measurement standards. The only reason we have a decimal system is because of the number of fingers we have. Hardly a sound reason to squeeze physical relations into. One wonders why there are 2.5mm screws when the decimal system works so well. If we'd had 8 finger, things would have been so much easier to work with. 8 is 2 cubed and one hand would be 4 or 2 squared. These both fit nicely into the physical world were squares cubes are most often worked with. Even logs would have made more sense under a base 8 system. > >I don't actually know where 50 and 60 Hz came from, nor 100 and 115 >and 220 and 240 volts. There may be some ancient justification in the >tinkerings of various 19th century engineers, but it seems to me it >makes most sense simply to view them as random numbers. I've been trying to find some actual history on the 50/60 thing on the net but so far, all I was able to find was that cell phones are frying our brains. My understanding was that it was a balance between efficient generation and efficient transformers. The voltages were mainly to control line loss. In the US, most people live close to their distribution transformer and line loss is not that high at 110-115V. Dwight > > paul > >

Indigo/SGI drives

by Saquinn624＠aol.com

On all of my replaced SCSI drives, I use SCA adaptors and SCA drives- much easier to get nowadays than 50 pin models, and also newer. Any drive will work-they do not need special firmware The deal for SGI sleds is as follows- The 50 pin cable goes into the 50 pin narrow SCSI socket on the adaptor- self explanitory The power cable will often need to be teased out a little longer (at least on Indigo2, I don't have my Indigo sled at hand) For the SCSI ID cable (the 6-pin bit) you will need a VOM/DMM. One side will have a bank of 3 wires, the other will have 1 wire. On the adaptor, there will be 3 pins wired together -> these are ground, connect to the single pin side. The other wires set the SCSI ID based on which slot in the Indigo the drive is installed If you choose to hardwire the drive (not as neat, but a definite possibility), remember that on IRISes the host adapter is ID 0, so the first (system) disk is ID 1- and so on. Most computers have the host adapter as ID #7, but not Siggys. Best of luck to you, they are very neat machines, with a slick UI (Indigo Magic)- For IRIX 5.3 be sure to get the free IDO (Development Option-compilers and headers, available from www.sgi.com) Scott Quinn

It might be a center tap or even just a ground lead that doesn't carry current. Since you have the box open, you should be able to see where all the wires go. Dwight

Are HP 2671's repairable?

by dwight.elvey＠amd.com

Hi Bob There used to be a place around here called Motion Industries. I believe they changed there name but they were a nation wide company and had branches across the nation. They carried all the standard cogged belts and such. I'm sure they'd have what you need. They might still have the same name or something similar. It has been a few years since I used them ( like about 10 or so ).

Off the wall CGA monitor question

by bob＠jfcl.com

Can anybody tell me if a "proper" (i.e. true IBM compatible) CGA (CGA, not MDA, EGA or VGA) monitor had a male or female connector? I know it had a DB-9 with approximately this pinout 1,2 Ground 3 Red 4 Green 5 Blue 6 Intensify 7 N/C 8 Hsync 9 Vsync All signals are TTL and active high, as I remember. Anybody in the SF Bay Area got a real CGA monitor that they don't want anymore? Thanks, Bob Armstrong
